  As shown in FIGS. 1 to 5, the back surface 2 of the camera 1 is provided with a display unit 10, an operation unit 15, and an opening / closing mechanism 20. The camera 1 according to the present embodiment can tilt the display unit 10 in two directions that are substantially perpendicular to the back surface 2 of the camera 1 (or camera housing). In the present embodiment, the display unit 10 is a display unit that is formed by a TFT LCD (Thin Film Transistor Driven Liquid Crystal Display) and can change display contents, but is not limited thereto. For example, other methods such as organic electronic luminescence may be adopted. Further, an electronic device in which the display unit 10 and the opening / closing mechanism 20 are combined is referred to as a display device.

  The opening / closing mechanism 20 includes a first shaft 21, a second shaft 31, a third shaft 41, and a fourth shaft 51 as a plurality of rotation shafts. The opening / closing mechanism 20 includes a first plate 22, a second plate 32, a third plate 42, and a fourth plate 52. In the following description, with reference to the operation unit 15, the short side far from the operation unit 15 is the side A 1, the short side opposite to the side A 1 is the side A 2, and the display unit 10 is in the storage state of the display unit 10. The long side facing the side A3 and the side A3 on the side is referred to as a side A4. When the display unit 10 is in the retracted state, the side A1 side is the left side of the camera 1, the side A2 side is the right side of the camera 1, the side A3 side is the lower side of the camera 1, and the side A4 side is the upper side of the camera 1.

  The first shaft 21 of the opening / closing mechanism 20 is a rotation shaft extending from the base plate 19 disposed on the back side of the camera housing, and is in the direction substantially parallel to the side A1 of the display unit 10. Is pivotally supported. The first axis 21 is arranged along the ridge line on the short side that is far from the operation unit 15 among the sides forming the back surface 2 of the camera housing.

  The second shaft 31 of the opening / closing mechanism 20 is opposite to the first shaft 21 of the first plate 22 and supports the second plate 32 rotatably in a direction substantially parallel to the first shaft 21. Yes.

  The second plate 32 is a sheet metal part having substantially the same size as a rectangular area when the display unit 10 is viewed from the display surface side (the back surface 2 side of the camera 1 in the housed state). In addition, the place where the 2nd axis | shaft 31 is pivotally supported is the one end part in the 1st plate 22, and the substantially central part in the long side of the display part 10 when it sees from the display surface side in the 2nd plate 32. Upper and lower ends. Here, the other end of the first plate is pivotally supported by the first shaft 21.

  The third shaft 41 of the opening / closing mechanism 20 is pivotally supported in the second plate 32 so as to be substantially parallel to the long side of the display unit 10 and to rotate the third plate 42 at a position along the side A3 of the display unit 10. doing.

  The fourth axis 51 of the opening / closing mechanism 20 is substantially parallel to the long side of the display unit 10 and the third axis 41 on the third plate 42, and at a position along the side A <b> 4 of the display unit 10. Is pivotally supported. The display unit 10 is fixed (held) to the fourth plate 52.

  Among the rotating shafts described above, the first shaft 21 and the second shaft 31, and the third shaft 41 and the fourth shaft 51 are substantially parallel rotating shafts. The first axis 21 and the second axis 31 are rotation axes that are substantially orthogonal to the third axis 41 and the fourth axis 51, respectively.

  Hereinafter, the tilting operation of the display unit 10 around each rotation axis will be described. When the tilt operation about the first axis 21 is performed, the display unit 10 is in the left tilt state illustrated in FIG. When the display unit 10 is in the left tilt state, the camera 1 is in a state suitable for, for example, a user holding the camera 1 in a vertical position and capturing a subject from a relatively high angle. When the tilt operation about the second axis 31 is performed, not only the second axis 31 but also the first axis 21 rotates in association with the display unit 10 in the right tilt state shown in FIG. It becomes. When the display unit 10 is in the right tilt state, the camera 1 is in a state that is suitable for the user to hold the camera 1 in the vertical position and capture a subject from a relatively low angle, for example. In the right tilt state of the display unit 10, the display unit 10 is separated from the operation unit 15, so that when the user operates the operation unit 15, the fingertip may accidentally touch the screen of the display unit 10. Can be prevented.

  Further, when the tilting operation about the third axis 41 is performed, the display unit 10 is in the lower tilt state illustrated in FIG. When the display unit 10 is in the downward tilt state, the camera 1 is in a state suitable for, for example, the user holding the camera 1 in the horizontal position (normal position) and imaging the subject from a relatively high angle. Further, when the tilting operation about the fourth axis 51 is performed, the display unit 10 is in the upper tilt state illustrated in FIG. The camera 1 when the display unit 10 is in the upward tilt state is, for example, a state in which the user holds the camera 1 in the lateral position (normal position) and is suitable for imaging a subject from a relatively low angle. In addition, it is suitable for confirming the display unit 10 from the subject side by further rotating the tilting operation about the fourth axis 51 about 180 ° so that the display surface of the display unit 10 faces the subject side. It becomes a state.

  FIG. 6 is a side view of the camera 1 according to the present embodiment as viewed from the left side, and is a diagram illustrating the side view of the state of the camera 1 in FIG. 5 exemplarily. The rib-shaped portion 53 provided on the top cover of the camera housing is disposed above the side A3 of the display unit 10 in the storage state of the display unit 10 and is closer to the back side of the camera 1 than the first shaft 21 (photographer). Side). It is desirable that the dimension of the rib-shaped portion 53 in the direction along the side A3 of the display unit 10 is substantially the same as the side A3 of the display unit 10. As described above, when the display unit 10 is tilted about 180 ° about the fourth axis 51 with respect to the camera housing, the display unit 10 can be confirmed from the subject side.

  At this time, since the display unit 10 comes into contact with the rib-shaped portion 53 prior to the first shaft 21, the display unit 10 stably contacts the rib-shaped portion 53. The display unit 10 can be directed toward the subject. That is, when the display unit 10 is tilted by about 180 ° around the fourth axis 51, the display unit 10 and the first shaft 21 can be prevented from contacting each other. Moreover, since it can suppress that the display part 10 contacts the 1st axis | shaft 21 by this structure, it can suppress that force acts only on a part of display surface of the display part 10. FIG. The rib-shaped portion 53 is close (adjacent) to the side A3 that is the long side of the display unit 10 in the storage state of the display unit 10, and forms the long side of the display device together with the side A3.

(Lock mechanism)
Next, a lock mechanism related to the tilt operation of the display unit 10 will be described with reference to FIGS. The camera 1 described above is capable of tilting the display unit 10 with the four axes of the first axis 21, the second axis 31, the third axis 41, and the fourth axis 51 as rotation axes. Here, if the tilt operation is performed independently about each rotation axis, the display unit 10 comes into contact with each unit such as the operation unit 15 disposed in the camera 1 and an operation not intended by the user is performed. May end up. Therefore, the camera 1 of the present embodiment includes a lock mechanism for restricting that the tilting operation about each rotation axis is independently performed. The details will be described below.

  The first lock mechanism 60 causes the tilt operation about the third axis 41 or the fourth axis 51 to be performed carelessly during the tilt operation about the first axis 21 or the second axis 31. It is the 1st rotation control means to prevent. FIG. 7 is a diagram illustratively showing an enlarged view of the first lock mechanism 60 when the display unit 10 is in the housed state according to the present embodiment. The first lock mechanism 60 includes a sloped portion 61, a movable part 62, and a compression coil spring 63. In order to simplify the description of the configuration of the first lock mechanism 60, the display unit 10 is not shown in FIG.

  The movable part 62 provided on the second plate 32 is movable toward the sides A3 and A4 (the vertical direction of the camera 1) of the display unit 10 and is urged toward the side A3 by the compression coil spring 63. Yes. When the display unit 10 is in the housed state, the movable part 62 receives an urging force from the compression coil spring 63 and comes into contact with the inclined surface part 61 provided in the camera 1. In the housed state of the display unit 10, the claw shape 62 a provided on the movable part 62 is located at a position (first unregulated position) where the tilt operation about the fourth axis 51 of the fourth plate 52 is not regulated. . In other words, when the display unit 10 is stored, the display unit 10 can be tilted in both the up and down directions.

  FIG. 8 is an exemplary view illustrating an enlarged view of the first lock mechanism 60 when the tilt operation is being performed around the first axis 21 of the display unit 10 according to the present embodiment. In addition, in order to simplify description of the structure of the 1st locking mechanism 60 similarly to FIG. 7, the display part 10 is not illustrated in FIG.

  As shown in FIG. 8, when the display unit 10 is in a tilt (left tilt) operation around the first axis 21, the contact state between the movable part 62 and the slope-shaped portion 61 is released by the left tilt operation. Is done. In this state, the movable component 62 moves to the third shaft 41 side (side A3 side) by the biasing force of the compression coil spring 63. When the movable part 62 moves to the side A3, the claw shape 62a moves to a position (first restriction position) that restricts the tilt operation (upper tilt operation) about the fourth axis 51 of the fourth plate 52. The display unit 10 is in the first locked state. In the first locked state, the second plate 32 and the fourth plate 52 can move integrally. In other words, in the first locked state of the display unit 10, the vertical tilting operation of the display unit 10 is restricted, and only the horizontal tilting operation is possible.

  When the display unit 10 is returned to the retracted state from the tilting operation in the left-right direction of the display unit 10 around the first axis 21 or the second axis 31 in the first locked state of the display unit 10, the display unit 10 The movable part 62 and the slope-shaped portion 61 come into contact with each other again just before the storage state is reached. And if the force which returns the display part 10 to an accommodation state exceeds the urging | biasing force of the compression coil spring 63, the nail | claw shape 62a of the movable part 62 will move to the side A4 side (upper side). In this state, the movable part 62 moves from a position (first restriction position) that restricts the tilt operation in the vertical direction of the display unit 10 to a position (first non-restriction position) that allows the tilt operation in the vertical direction. And move. That is, when the claw shape 62a is out of the position where the movement of the fourth plate 52 is restricted, the tilting operation with the third axis 41 and the fourth axis 51 as the rotation center can be performed again.

  The camera 1 is also provided with a second lock mechanism 70 so that the first shaft 21 and the second shaft 31 do not operate unexpectedly. FIG. 9 is a diagram illustrating an example of a cross-sectional view of the second lock mechanism 70 in a state where the display unit 10 according to the present embodiment is stored. FIG. 9 is a cross-sectional view in a direction perpendicular to the first axis 21 when the display unit 10 is in the stored state.

  The second lock mechanism 70 causes the tilt operation about the first axis 21 or the second axis 31 to be performed carelessly during the tilt operation about the third axis 41 or the fourth axis 51. It is the 2nd rotation control means to prevent. As shown in FIG. 9, the second lock mechanism 70 includes a lock release lever 71, a lock connecting portion 72, a lock claw slope portion 73, and a spring member (not shown).

  The second locking mechanism 70 is movable to the side A1 and the side A2 side of the display unit 10, for example, in the storage state of the display unit 10, for example, the side A1 side by a spring member (not shown) provided in the camera 1 Is being energized.

  As illustrated in FIG. 9, in the storage state of the display unit 10, the lock claw slope portion 73 enters the movable region of the first plate 22, and the first plate 22 and the lock claw slope portion 73 are engaged. In this state, the second lock mechanism 70 moves to a position (second restricting position) where the tilt operation with the first axis 21 or the second axis 31 of the display unit 10 as the rotation center is possible. In other words, in this state, the display unit 10 is restricted from tilting in the left-right direction around the first axis 21 and the second axis 31 and is centered on the third axis 41 and the fourth axis 51. Tilt operation in the vertical direction is possible.

  FIG. 10 is a diagram illustratively showing a cross-sectional view of the second lock mechanism 70 during the tilting operation in which the display unit 10 according to the present embodiment has the first axis 21 as the rotation center. FIG. 10 is a cross-sectional view in the direction orthogonal to the first axis 21 as in FIG. 9.

  As shown in FIG. 10, when the user depresses the lock release lever 71 in the direction of arrow A indicated by a broken line, the lock claw slope portion 73 moves out of the movable region of the first plate 22, The engagement with the lock claw slope portion 73 is released. In this state, the second lock mechanism 70 moves to a position (second unregulated position) where the tilt operation with the first axis 21 or the second axis 31 of the display unit 10 as the rotation center is possible. Note that the right tilt operation with the first axis 21 as the center of rotation is possible, so that the right tilt operation with the second axis 31 as the center of rotation is also possible.

  When the display unit 10 is returned to the storage state, the lock claw slope portion 73 and the first plate 22 come into contact again immediately before the display unit 10 enters the storage state. In this state, when the force to return the display unit 10 to the stored state exceeds the biasing force of a spring member (not shown), the lock claw slope part 73 moves to the side A2 side, and the lock claw slope part 73 is moved to the first plate. Retreat from the 22 movable areas. And the 1st plate 22 becomes movable in the whole movable area | region, and the display part 10 will be in an accommodation state. By engaging the first plate 22 after the lock claw slope portion 73 that enters the storage state of the display unit 10 again enters the movable region of the first plate 22 by the biasing force of a spring (not shown), the first plate 22 is engaged. Tilt operation around the axis 21 is restricted.

  As described above, the camera 1 of the present embodiment can tilt the display unit 10 in the vertical direction at least in a state other than the state where the lock by the second lock mechanism is released, and tilt in the horizontal direction. Operation is restricted. In other words, even if the lock by the second lock mechanism is released, the tilting operation in the vertical direction of the display unit 10 is possible if the lock by the first lock mechanism is released.

  On the other hand, the camera 1 can tilt the display unit 10 in the left-right direction in response to the release of the first lock mechanism 60 after the lock of the second lock mechanism is released. In other words, the camera 1 can tilt the display unit 10 in the vertical direction without releasing the first and second locking mechanisms, but must release both the first and second locking mechanisms. In this configuration, the tilting operation in the left-right direction cannot be performed. In other words, the camera 1 of the present embodiment can perform a tilting operation in the left-right direction around the first axis 21 or the second axis 31 of the display unit 10 as long as the user does not press the lock release lever 71. It is a configuration that cannot be done.

  With this configuration, the camera 1 of the present embodiment can prevent each tilting operation of the display unit 10 from being performed independently, and can suppress an operation not intended by the user from being performed. Furthermore, with the above-described configuration, the camera 1 according to the present embodiment can preferentially execute the tilt operation in the vertical direction over the tilt operation in the horizontal direction of the display unit 10. In general, since the imaging apparatus is often held in a horizontal position to image a subject, the camera 1 according to the present embodiment can preferentially perform a tilting operation in a horizontal position that is frequently used. By adopting, the operability of the camera 1 by the user can be improved.

  In the present embodiment, in the storage state of the camera 1, the arrangement of the plates in the optical axis direction is from the base plate 19 toward the display surface side, the first plate 22, the second plate 32, the third plate 42, and the fourth. Although it arrange | positions in order of the plate 52, it is not limited to this. For example, in the configuration in which the horizontal tilt operation of the display unit 10 is prioritized over the information item tilt operation, the third plate 42, the fourth plate 52, the first plate 22, and the second plate are selected from the imaging direction in the storage state. 32 may be arranged in order. In other words, the arrangement order of the optical axis directions (in the housed state) of the plates may be different in accordance with the priority operation among the vertical and horizontal tilt operations of the display unit 10. .

(Arrangement of flexible cable 80)
Next, a method for arranging the flexible cable 80 for electrically connecting the display unit 10 and the camera housing will be described with reference to FIGS. 2 to 5 and FIGS. 11 to 12. Inside the opening / closing mechanism 20, a flexible cable 80, which is a communication means for electrically connecting the camera housing side and the display unit 10, is disposed.

  As shown in FIG. 2, the flexible cable 80 is in the vicinity of the first shaft 21, and the side A <b> 2 of the display unit 10 from the back side of the camera housing close to the side A <b> 1 in the storage state of the display unit 10. It is pulled out to the side and disposed on the surface of the first plate 22. As shown in FIG. 3, a first guard member 81 is provided from the vicinity of the outlet of the flexible cable 80 on the camera housing side to the vicinity of the second shaft 31 in order to prevent the user from contacting the flexible cable 80. Yes. As shown in FIGS. 2 and 3, the flexible cable 80 passes between the first plate 22 and the first guard member 81 and is close to the second plate 32 in the vicinity of the second shaft 31.

  The flexible cable 80 is arranged along the surface of the second plate 32, with the direction of routing being changed in the direction of the side A <b> 3 on the surface of the second plate 32. As shown in FIG. 2, the second plate 32 is provided with a second guard member 82, and the flexible cable 80 passes between the second plate 32 and the second guard member 82 and is in the vicinity of the third shaft 41. And close to the third plate 42.

  The flexible cable 80 is routed in the direction of the side A4 on the surface of the third plate 42 and is disposed along the surface of the third plate 42. A third guard member 83 is provided on the third plate 42, and the flexible cable 80 passes between the third plate 42 and the third guard member 83, crosses the display portion in the vicinity of the fourth shaft 51, It is connected to a display substrate (not shown) of the display unit 10 while being close to the plate 52.

  Note that the flexible cable 80 according to the present embodiment is not necessarily arranged at the rotation center in each tilting operation of the opening / closing mechanism 20. In this case, the required path length of the flexible cable 80 changes due to the tilting operation of the display unit 10. For example, when the length of the flexible cable 80 is shorter than the required path length after the change, the display unit 10 cannot be tilted to a predetermined position, and the flexible cable is obtained by forcibly performing the tilting operation in this state. 80 may be damaged. Further, for example, when the length of the flexible cable 80 is longer than the required path length after the change, the flexible cable 80 is slackened, and thus the slacked flexible cable 80 may be caught during the tilting operation. .

  Therefore, the camera 1 of the present embodiment has a structure that absorbs the change in the extra length of the flexible cable 80 in the second guard member 82, and the necessary path of the flexible cable 80 according to the tilting operation of the display unit 10 by this configuration. Responds to changes in length.

  FIG. 11 is a diagram illustrating the second guard member 82 according to this embodiment. 12 is a cross-sectional view taken along the line A-A ′ shown in FIG. 11 in a state where the flexible cable 80 is attached to the second guard member 82 shown in FIG. 11. FIG. 12 is a diagram illustrating the flexible cable 80 in the storage state of the display unit 10.

  As shown in FIG. 11, the second guard member 82 is provided with a first flexible folded portion 82a and a second flexible folded portion 82b as a plurality of folding means capable of elastic deformation. As illustrated in FIG. 12, when the display unit 10 is in the housed state, the flexible cable 80 is folded back by the first flexible folded part 82 a and the second flexible folded part 82 b of the second guard member 82.

  When a tilt (left tilt) operation with the first axis 21 as the rotation center is performed, the required path length of the flexible cable 80 from the flexible drawer portion of the camera housing to the second guard member 82 is the display unit 10. Is longer than when it is stored. In this state, the tension applied to the flexible cable 80 increases due to a change in the required path length of the flexible cable 80. Then, due to the increase in the tension, the first flexible folded portion 82a and the second flexible folded portion 82b are elastically deformed to positions as illustrated by a two-dot chain line in FIG. With this configuration, the required path length of the flexible cable 80 between the plurality of folded portions 80a and 80b of the flexible cable 80 is shortened. With this configuration, the amount of change in the path length due to the elastic deformation of the first flexible folded portion 82a and the second flexible folded portion 82b and the flexibility when the tilt operation is performed when the first shaft 21 is the rotation center are performed. The amount of change in the path length between the folded portions of the cable 80 becomes equal. Therefore, by adopting the above, the opening / closing operation of the display unit 10 is performed smoothly. In the above-described embodiment, only the left tilt operation of the display unit 10 has been described. However, substantially the same configuration as the above-described second guard member 82 so as to correspond to the tilt operation with the other rotation axis as the rotation center. It is applicable to the tilting operation of the display unit 10 related to each rotation axis.

  In the camera 1 of the present embodiment, the first lock mechanism 60, the second lock mechanism 70, the first flexible folded portion 82c, and the second flexible folded portion 82d overlap each other in a direction parallel to the optical axis. It is placed in a position that does not. With this configuration, an increase in the dimension of the camera 1 in the thickness direction (direction parallel to the optical axis) can be suppressed.

  By adopting the configuration described above, the camera 1 of the present embodiment is a mechanism for sliding the display unit 10 to avoid interference between the camera housing and the display unit 10 in the tilting operation of the display unit 10. There is no need to provide. That is, the camera 1 of the present embodiment can reduce the increase in the size of the mechanism that allows the display device to rotate in a plurality of directions with respect to the held housing.

  The display unit 10 is configured to be rotatable about a plurality of rotation axes with respect to the camera casing, and the display surface of the display unit 10 can be directed in four different directions. With this configuration, the display direction of the display unit 10 can be changed to a state suitable for imaging a subject at a high angle and a low angle regardless of the holding state of the camera 1 (or display device) by the user.

  As mentioned above, although preferable embodiment of this invention was described, this invention is not limited to these embodiment, A various deformation | transformation and change are possible within the range of the meaning.
